Just like you said popeye67 , i found it in integrated peripherals drop down menu . And I've changed the IDE to Raid setup , thnx to you .

But what bothers me is the serial port option which i saw just above it , just like to know what actually are the serial ports for , coz i cant recollect any hard wares that i installed which needed a serial port .

As I'm new to tweaking field , would something terrible happen if i alter the default memory timings , voltages , cpu multiplier and FSB little by little.

If something goes wrong what must be done to bring the BIOS back to its formal state , can we set any backup .
